Indirect Cost Rate Calculator
Calculate NICRA or flat indirect cost rate from total indirect and direct costs. Enter values for instant results with step-by-step formulas.
Formula
IDC Rate = (Total Indirect Costs / Cost Base) x 100
Where Total Indirect Costs include all overhead expenses not directly attributable to a specific project, and Cost Base is either Total Direct Costs (TDC), Modified Total Direct Costs (MTDC), or Salaries and Wages depending on the methodology. MTDC excludes equipment over $5,000 and subaward amounts over $25,000.
Worked Examples
Example 1: Calculating a NICRA-based Indirect Cost Rate
Problem: An NGO has $500,000 in total direct costs, $450,000 in MTDC (excluding equipment over $5,000), and $90,000 in indirect costs. Calculate the IDC rate using MTDC base.
Solution: IDC Rate = Indirect Costs / MTDC x 100\nIDC Rate = $90,000 / $450,000 x 100 = 20%\nThis means for every $1 of MTDC, the organization charges $0.20 in indirect costs.\nTotal budget = $500,000 + $90,000 = $590,000
Result: Indirect Cost Rate: 20% of MTDC | Total budget with overhead: $590,000
Example 2: De Minimis Rate Calculation
Problem: A small nonprofit without a NICRA has direct costs of $200,000 and MTDC of $180,000. Calculate indirect cost recovery using the 10% de minimis rate.
Solution: De minimis indirect costs = MTDC x 10%\nIndirect costs = $180,000 x 0.10 = $18,000\nTotal project budget = $200,000 + $18,000 = $218,000\nIndirect as % of total = $18,000 / $218,000 = 8.3%
Result: Indirect cost recovery: $18,000 | Total budget: $218,000
Frequently Asked Questions
What is an indirect cost rate and why is it important for NGOs?
An indirect cost rate, also known as an overhead rate, is the ratio of an organization's indirect costs to its direct cost base, expressed as a percentage. Indirect costs are expenses that cannot be directly attributed to a single project or grant but are necessary for the organization to operate, such as rent, utilities, administrative staff salaries, accounting, human resources, and general management. For NGOs and nonprofits, having a properly calculated and documented indirect cost rate is critical for grant applications, particularly with federal funders like USAID, the Department of State, and the National Science Foundation. A negotiated indirect cost rate agreement (NICRA) with the federal government establishes the approved rate at which organizations can charge overhead to federal grants, ensuring full cost recovery and organizational sustainability.
What is the difference between NICRA and de minimis indirect cost rates?
A Negotiated Indirect Cost Rate Agreement (NICRA) is a formal agreement between an organization and its cognizant federal agency that establishes the percentage of indirect costs that can be charged to federal awards. The NICRA is based on actual audited financial data and typically produces a rate that reflects the true cost structure of the organization, often ranging from 15% to 60% or higher for well-established organizations. The de minimis rate, established under 2 CFR Part 200, is a flat 10% of Modified Total Direct Costs (MTDC) available to organizations that have never had a NICRA. While simpler to implement, the de minimis rate often underrecovers true indirect costs. Organizations must choose between the de minimis rate and negotiating a NICRA, and once they have a NICRA, they generally cannot revert to de minimis for federal awards.
Can an organization have different indirect cost rates for different funders?
Yes, organizations can and often do apply different indirect cost rates depending on the funder and grant requirements. While a NICRA establishes the maximum rate for federal awards, individual federal grants may cap the indirect cost rate below the negotiated rate. For example, some USAID mechanisms cap indirect costs at specific percentages regardless of the organizations NICRA. Private foundations often have their own overhead policies, with some allowing no indirect costs and others permitting rates ranging from 5% to 20%. State and local government grants may set their own caps. Organizations must carefully track which rate applies to each funding source to ensure compliance. When a funder restricts the indirect cost rate below the NICRA rate, the difference represents unrecovered indirect costs that the organization must fund from other sources, impacting overall financial sustainability.
